I'm back playing after MANY years of not - and I've forgotten a lot of the basics. Right now, I have the sheet music for the Bach Air from the 3rd suite. I'm wondering about this - and all other music, for that matter - when determining fingerings. Are there some basic "truths" about fingerings that I should attend to as I set about trying to find the best way to play this? All I'm trying to do at this point is avoid open strings most of the time. Can I get any guidance on this? Thanks! CC
